文题释义:
异种松质骨:作为天然骨组织工程支架来源,虽其抗原性强,但其来源广、成本低、便于加工且经过特定处理,如脱蛋白、煅烧、脱脂、冻干等,可减低或消除免疫原性,在作为骨缺损修复材料上有着巨大潜能。
牛、猪松质骨:与人松质骨在理化性质上存在着一定的差异,在选择天然衍生骨材料来源时应该考虑到其中存在的差异性,如在脱钙多孔支架的天然骨原料选择上,猪松质骨中蛋白质的量比牛骨中含量高,提示二者胶原含量的差异应引起研究者的注意。微型猪的Ca/P最高,这可能说明其中含有更多的杂质,或是其羟基磷灰石中含钙量更接近化学成分的羟基磷灰石,在选择天然衍生骨修复材料时,材料的Ca/P对支架材料机械性能与可能对间充质干细胞的成骨性影响亦应该得到重视。

摘要
背景:研究表明,异种松质骨衍生骨移植修复材料具有骨缺损修复能力,但鲜有异种骨与人骨成分对比的报道。
目的:分析猪、牛、人胫骨上端松质骨的化学成分、无机物相、钙磷含量、总蛋白质含量及形貌。
方法:将普通猪、牛、版纳微型猪、年轻人、老年人胫骨上端松质骨片切成0.5 cm×0.5 cm×0.5 cm大小的骨粒,根据不同的检测目的进行脱脂、干燥等预处理,采用傅里叶红外光谱、X射线衍射、等离子体发射光谱仪、扫描电镜、凯氏定氮法检测其化学成分、无机物相、钙磷含量、蛋白质含量,采用Nano Measurer 1.2与Photoshop cs6直方图功能分析电镜结果,测孔径与孔率。
结果与结论:①5种松质骨的主要无机物相为羟基磷灰石,无机质成分主要为磷酸盐类与碳酸盐类;②牛松质骨中钙含量低于其余4种松质骨(P < 0.05),年轻人松质骨磷含量高于猪、牛松质骨(P < 0.01),普通猪与版纳微型猪松质骨中蛋白含量高于其余3种松质骨(P < 0.05);③5种松质骨的孔径均值在400-600 μm间,孔率在60%-70%间,并且以牛松质骨孔率最大;④结果表明,猪、牛松质骨在有机与无机物成分上与人骨存在一定的差异。

Abstract:

BACKGROUND: Existing evidence has shown that xenogeneic bone derived graft materials have the ability to repair bone defects, but little report is on the comparison of composition of xenogeneic bone and human bone.
OBJECTIVE: To analyze the chemical composition, mineral phase, calcium and phosphorus contents, total protein contents, and appearance of the cancellous bones of the tibia from pig, bovine and human.
METHODS: Cancellous bones of the tibia from pig, Banna miniature pig, bovine, young and old people were cut into bone particles of 0.5 cm×0.5 cm×0.5 cm. After degreasing or drying treatment, chemical composition, mineral phase, calcium and phosphorus contents, total protein contents of bone particles were detected using Fourier transform infrared spectroscopy, X-ray diffraction, plasma emission spectroscopy, scanning electron microscopy, and Kjeldahl method, respectively. Nano Measurer 1.2 and Photoshop cs6 were used to measure pore diameter and porosity rate based on the results of scanning electron microscope.
RESULTS AND CONCLUSION: The main inorganic phase of five kinds of cancellous bones was hydroxyapatite and the main chemical composition was phosphate and carbonate. The calcium content of the bovine cancellous bonewas lower than that of the other cancellous bones (P < 0.05) and the phosphorus content of the cacellous bone of young man was higher than that of the pig and bovine cancellous bones (P < 0.01). The total protein content in the cancellous bones of normal pig and Banna miniature pig was higher than that in the other three kinds of cancellous bones (P < 0.05). The pore diameter of five kinds of cancellous bones was 400 to 600 μm and the porosity rate was 60% to 70%. Moreover, the porosity rate of the bovine cancellous bone was the highest. Therefore, we conclude that there are some certain differences in the organic and inorganic components of the pig or bovine cancellous bones as compared with humans.
